Cold Air Guns

U.S. Metric

Product Overview

Versatile Spot Cooling for Machining, Repair Shops and More

Cold Air Guns use vortex tube technology and filtered compressed air to produce sub-freezing air as low as -30 deg F for numerous industrial spot cooling applications. With no moving parts to wear out, Cold Air Guns require no electricity at the target, just a compressed air source.

Cold Air Guns are most often used for cooling of metal parts, in the machining and repair of metals, plastics, wood, ceramics and other materials. Cold air machining outperforms mist coolants and substantially increases tool life and feed rates on dry machining operations. The effective cooling from a Cold Air Gun can eliminate heat-related parts growth while improving parts tolerance and surface finish quality. Cold Air Guns have adjustable temperature and flow settings; and some models have a frost free nozzle to eliminate mess from frost and condensation.

Vortec Frost Free Cold Air Gun

The Frost Free Cold Air Gun cools tools quickly and without the mess of liquid lubricants or frost from standard cold air guns. Used in a wide variety of applications including cutting and drilling, and will increase tool life and feed rates in dry machining operations.

Vortec Cold Air Pistol

The Cold Air Pistol delivers spot cooling on demand, for cooling parts and welds, speeds tool changes, sets adhesives and hot melts, and facilitates thermal cycling. Here the Cold Air Pistol spot cools hot bearings after installation on the shaft. The Cold Air Pistol cools instantaneously, cooling quickly and with no liquid mess.

Cold Air Gun in an OEM Application

MAG uses the Vortec Cold Air Gun in their VIPER® Fiber Placement Systems to improve the quality of the aerospace parts produced by VIPER. The Cold Air Gun chills and conditions the pre-impregnated graphite fiber resin, making it easier to dispense and resulting in the highest possible dexterity, flexibility and range for large to complex aerospace parts.

Case Studies

Cold Air Gun Improves Production Rates & Quality in Paper Production:

High heat on a 40” saw blade caused Carolina Paper Company to suspend production frequently to allow the blade to cool. After installing the Vortec Cold Air Gun, production rates improved by 42% and scorching was eliminated.
